Saint Petersburg's air quality reflects the flat Finnish Gulf coastal position on the Neva River delta at sea level, with vehicle traffic on surrounding roads and the vehicle density, industrial, and heating corridor generating elevated PM2.5. The Gulf of Finland's Baltic maritime influence provides coastal ventilation, while winter anticyclonic inversions concentrate heating and industrial emissions and summer wildfire smoke from surrounding Russian forests represents a growing seasonal concern throughout the year.

When is air pollution at its worst in Saint Petersburg?
Pollution in Saint Petersburg typically rises when traffic emissions as well as wood-burning stoves combine, especially once dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Saint Petersburg based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
